  [VectorCombine] foldSelectShuffle - remove extra adds of old shuffles to worklist (#127999)

We already push the old shuffles to the worklist as part of the replaceValue calls, so we shouldn't need to add them to the deferred list as well - my guess is this was to ensure that the instructions got erased first to help cleanup unused instructions, but eraseInstruction should handle this now.
